To all/whom# may concern:

Be it known that we, WASHINGTON A. PEASLEE and JOHN O. D. LILLY, ofIndianapolis, in the county of Marion and State of Indiana, haveinvented a new an'd useful `Improvement in Chimneys and Spark-Arrestersfor Locomotives; and we hereby declare that the following is a full' andexact description.

The nature of our invention consists in providing a perforated sparkand` smoke cone-within the chimney stack properand forcing, or drawingall the products of combustion through the perforations by a centrifugalaction given to said products by means of a` continuous current ofexhaust steam passed up along the outside of this side of the chimney.In this way, a more` perfect and uniform exhaust is kept up andmlaintained, than'by any of the other known ans. p To enable others,skilled in the art, to manufacture and use our invention, wewill nowproceed to describeits construction and operation.

Figure l, is an elevation of chimney and smoke arch, box, or reservoir,(viewed from the standpoint of the engineer in his cab) showingthemanner in` which the exhaust pipes enter the said chimney-also thewaste pipe for redundant sparks, that are arrested in their outward`passage. i Fig. 2, is an elevated view ofthe perforated cone, throughwhich all the products of combustion` make their escape.` Fig. 3, is anelevated sectional view of the chimney,perforated cena-waste sparktuba-saddle for chimney, and all else pertaining to the device. Fig.4,is aview of the chimney saddle, and the lower inclined planes-by meansof which the `escape throat is enlarged, or di,- minished, at the willof the engineer. Fig. 5, is an elevated view of the collar whichsurrounds the escape throat, and which also supports the outer chimneycase.` Fig. 6 is an elevated view ofthe above collar propershowing thepins and, by dotted` lines the inclined slots in which these pins play,to

elevate, or depress the chimney. Fig. 7, is`

a top viewof the chimney and the perforatedcone within. Fig. 8` is anunderside view of the saddle showing the manner in which the exhaustpipes enter it;\\als othe relative` position of the tube, for waste`sparks, to these exhaust steam pipes.`

The supplementary exhaust collars `c,agnflf` l 1 e, are` so arrangedastoiallowfthe exhaustf .l steam to pass up between them` the exhauststeam bein first admitted underneath them,"` in the sad leB, threugh`the two pipesfs, 18,5 n and from thence distributed around the@ eni 119tire circumference of the collane, betweeir` l` it and the collar,0,-`thencepassing.ummpdg` 1" between the perforated cone D, and theexternal stack C', to the place of egress at the top of chimney. l

d', andV d', are pins projecting from the collar, c, these pins slidingin the inclinejlane slots, indicated by the dotted lines in s, s, beingthe steam exhaust pipesthese passing u into the saddle B through thesmoke arc i, (from lateral points,) having their termination in anannular space surrounding the base of the perforated cone D-thedirection the steam takes is indicated by the double barbed arrows-thusin contradistinction to the direction of the products of combustion, asindicated by the single barbed arrows.

By reference F to Fig. 3, it will be seen that there is an adjustablethroator annular outlet for the steam, in passing from the exhaustpipes, s, s,-which is marked by the letters T, T; this throat can beenlarged, or contracted by the rotation of theV saddle collar c, throughthe intervention of lever h; passing it to the left, lifts the chimney,or smoke stack-and thus contracts the said Athroat; while passing to theright, lowers one on the immovable projection of saddle B, and the otheron the inside of collar c. Now, when collar, c, is dropped below theother, the throat for the passage of steam is enlarged, but, when raisedso as to bring these projections opposite, the said steam throat iscontracted to its smallest dimensions.

The advantages we claim for this invention over all others, constituteto some extent its plea of novelty in an economical point of view;-itsphilosophical adaptation to the functions it has to perform,completes-as we verily believeits claims to superior novelty andpractical usefulness over any and all other locomotive chimneys.

These points are more fully explained in the following description ofthe operation of our invention: viz: The flame, and products ofcombustion, pass up into the perforated cone D, around the spark wastepipe, s, and escape from this cone into the steamchamber-centrifugally-and, thence up and out at the top of chimney, C.The exhaust steam passes up the pipes-s, s,- through the throat T, intothe annular space, around the perforated cone, (and within the chimneyC,) to the place of egress at the top of same.

Now we are aware that it is no new thing to form a draft of air for themore perfect riddance of smoke, sparks, &c., by means of a current ofsteam, as experiments in Ewbanks Hydraulics amd Mechanics aredelineated, where steam is used for the elevation of water 1ttc., but,in all such experiments the steam is passed up through a central tube,or nozzle, the draft acting upon a substance or substances on theoutside of said current of steam. This peculiar feature of all knownplans, similar to this, is

mentioned, in order that the real operation,

or rationale, of our mode of producing a draft, 'may be more fullycomprehended. We pass the steam up, on th'e outside of the smoke,sparks, &`c., and by so doing .we not only bring a larger proportion ofsteam to bear upon these products of combustionthan the reverse planYwould do*but, by surrounding the escaping sparks &c. with steam weeectually drown out and extinguish all supernatant sparks, &c. Thealdvantages of this are self-evident. In this arrangement of ours, thesteam is forced upV the chimney with such a velocity as to suck, or drawthe air, smoke, &c. from the furnace, through the flues, and up theperforated cone, and thence out at the top of chimney through theperforations-as indicated by the course of the single barbed arrows. Y Y

When we desire to raise steam, in an yengine boiler speedily, we simplyrotate the collar, c, so as to contract the throat T, and, when asufficient supply is produced We rotate it back and so enlarge thissteam throat to suit the exigencies.

To prevent the condensation of steam in the `chimney (and consequentlyto prevent a retardation of its velocity) we contemplate surrounding thechimney C, with a wooden jacket during cold weather. This is not shownin our model or drawings, and, of course is optional with the users,and, in equatorial localities is not needed at all.

Observe the tunnel S, at the top of spark tube S, and the direction ofthe curved arrows over it. These arrows indicate the direction ofsupernatant and large sparkstoo large to escape through the perforationsof the cone D. As they are drawn up the coneseeking egress into thesteam channel without-they strike the pyramidal apex of said cone, andso, with a rebound, are caused to drop back into the tunnel S, andthence by their own gravity (being away now from the drawing influencesof the steam) drop down through the tube S, into the bath box b, where,a constant supply of water drowns them out.

We are aware that returning sparks simply from the top ofthe chimney, isnot new, but, no one has hitherto returned them in such way as toutterlypreclude the possibility of choking the tube which conducts them-ourtube passing down perpendicularly, while others pass at an angle offortyve degrees-and, at the same time, are necessarily much longer. l

In applying our invention to any common locomotive, no cutting, ormutilation is required, more than simply the cutting of two holes forthe egress of the steam pipes s, s, as seen in Fig. 8. These holes arecovered and guarded `by the cast-iron saddle B. The chimney is simple inconstruction, light in Weight, cheap, and besides performing thefunctions of a most perfect draft for the fire and spark arrester, andextinguisher, (all of which it performs in a superior degree) is durableto an extent equaled only by its exact adaptation to the purposes forwhich it is designed.

Having now described our invention in 15p full, what We claim asnevv,and desire to secure by Letters Patentis`f` V The constructionl ofa ch'lney, or spark arrester, by the `combination andarrangement of thevarious parts,substantially asgzp they are described in the foregoingspecifica-,U v tion, and for the purposes mentioned. y i
